This invention relates to improved :attachment means for the reel'b'se'of a fishing rod on its seat. Y

The object ofthe' invention is toiprovide attachment means forfastening: the reel base to the corresponding seatrportion of the rodwhich is of simple, durable. and inexpensive construction, at the sametime of: perfectlyreliable function as to ffixing the relative positionofthetwo members, and of the greatest convenience I in assembling ordisassembling theparts. Another'object is toform theattachment means insuch a :manner that "the reel base can be made symmetrical and be placedonthe rod seatfivith one and thesame end either pointing to the front orto the rear end ofthe rod.

Howthesevarious endsand still other advantages ,have been obtained, willappear fromthe subsequent description of the inventionun connectionwith:the drawings, both,

of which exemplify the design vpreferred at the present time. 1

. Referring now to the drawings, Figs. ,1 to 41nore particularly, .itwill be noted that my arrangementconsists ofthreeparts whi'ch'ari atubular seat member '1 which forms partof the fish rod adjacentthehand'le-th-ereoi; a reel base 10? which isnsually an-integra-l partof the reel proper notshown in the figure,

This ring is made from resilient: material such as steel and by virtueof its oval-shape it consists I of portions of greater or lesser-e0centricity with respecttothe axis of'the tubular seat member. Byholding'theringabout the seat tubewith. its more eccentric portionsuppermost,ithe ring opening will permitthe I'ingtobe slid over theassembled base plate: and-seat member sothat it may assume-a position onthe axis of the'tube as shown in Figil. Its radial position may then hechanged until it assumes the relation represented'in 'l igs. 1

and with the eccentric portion depending. Inthis position, as willappear later onfthe ringtightly locks thefreel and the seattoother.iTherlisassembling of theparts is 'e f fected by, going through thereversei-order'of ring movements. v

.The :seatitnbe'isnear one of itsends prd' Vided' with a flat pocketformed by-aZpa tch S of metalsheet-soldered or, in some othersuitableway, joined to the outer surfaceof the tube and extending. over asegment of the tube circumference; Aislot 4 in thepatchex tends'forsomedistance parallelwith-andnear the topeningmargin of the pocket.

The. reel base plate which is shorter in lengththanthe seat tube has abearing-face, the contour of which fits'the curvature of the tube and Ilaterally covers a segment ofi-som'e- I what smaller width .thanthepocket. Each endof the base plate terminates in:a-sin 1i lar u'pstandingflange portion 1-1 which portions are preferably struck upfrom-ttheb'ase rplate. The upstanding broken "awaystuds 12 be1o'ng tothe connecting portions between the l'r'eel proper, not shown inth'efigure,-andlthe'reel base plate.

In order to assemble 'the b'ase plate lo or the reel respectively on-theseatitube lgthe plate is held axially aligned, but to a certain; degreeinclined with respect to --theltubefand then with its inclined endinserted Tinthe pocket and gradually swung down into 10011 tiguousrelation with the-tube, whereby the slot-4 and the inserted flange 11will engage as a hook .andeye. fSinceth-e lateral-:e'xten ring.

highly resilient:

sion of the flange snugly fits the width of the slot, this end of thebase plate is securely held against any peripheral movements and,besides, the whole plate is fixed against any axial displacement.

It is manifest that with this construction it is immaterial which of thetwo end flanges is selected for introduction in the pocket since thereel proper is mounted on a perfectly symmetrical base plate. Thisreversibility is a very valuable feature of my construction. Reels aresometimes used in up.- right position on the rod, sometimes in dependingposition, and left and right handed persons require a diflerentpositioning of the reels for obtaining the for the line. All suchvarious requirements can be met by a symmetric reel constructionaccording to. this invention by simply inserting the base plate withproper heed to the desired winding sense.

. After the hook and eye engagement has been made in the simple mannerdescribed before, all that remains to be done for completely fixing theposition of the reelplate is to shove the'ring 20 over the other endflange 11 and then to turn it by 180 degrees. These manipulations of thering are facilitated by a rolled up or head portion 21 of the Thefunctioning of the ring as locking means will be best explained byreferring to the schematic illustrations Figs. 5 to 7.

The ring asmentioned already is of some material such as steel and my,therefore, be temporarily deformed or d ectedwhen being turned about asolid contour not in conformity to its interior outline'or opening. Inall of the Figures 5 to 7, the ringis' shown in its normal or non-de-Fig. 5 shows the relative position of'the various elements while thering is ready to be shoved over the flange 11 of the base plate. Thisflange is indicated in broken lines and shows how there is justsufiicient play for the ring to be slipped over the flange. Fig. 6 is apicture illustrating how the cross sectional area of the undeflectedring in its tightly locking relation corresponding to a 180 degree turnfrom its initial position, would cut into the cross section of the seattube between the points a and b on each side of the tube. Fig. 7 is asimilar picture ofthe ring when turned by 45 degrees out of its lockingposition of Fig. 6 and is, therefore, characteristic of the intermediatering positions while passing from shoving to locking position orconversely. The cut-in portions are insuch intermediate positionsunsymmetrical and in the case of Fig. 7 distribut'ed between theintersections 0, d and e, f, respectively. It will also be noted fromthis figurethat the cutting or overlapping areas in total are muchlarger in this case than they were in the locking position. This correctwinding sense.

amounts to saying that the ring, while being turned from its shoving toits locking position, passes through a series of elastic states whichstart with zero deflection, reach a maximum deflection and then dropagain to a certain locking deflection as given by Fig. 6. Since theseconditions are determined by the relative position of the ring and thebase plate, it follows that in the locking position these two membersare in a definite and stable relation with respect to each other, andthat any forces trying to change this position are checked from doing soby elastic forces of deformation set up in the assembling. It has beenfound from actual constructions that these forces provide ample safetyagainst any normal tendencies to dislocate the nonpockcted end of thebase plate on the rod, and this fact is further explained if oneconsiders that any relative rotation between the ring and base plateencounters a wedging resistance in the interspaces marked by w in Fig. 6between the ring and the seat tube. On the other and, the eccentricportion 22 of the ring offers a convenient thumb rest and turning leverfor moving the ring about its axis so that the normal effort of a personsuflices to turn the ring in and out of its locking position.

After having described my invention in a detailed manner, I wish topoint out some further advantages besides those already mentioned ascompared to former constructions.

All cooperating elements of this assembling are of most simple shapes,and each of them can be inexpensively formed in pressing or stampingmachines. The tubular seat body, forinstance, can be manufactured in oneand the same machine job since it need not have any depressions orridges as former structures required.

The absence of all precision machine work such as tapering, screwhreadedor toothed elements does not, only simplify and chealpen the manufacturebut renders this assemb mg much more reliable in service. Fishing rodsand their requisites are frequently exposed to adverse conditions suchas corrosive water, fine abrasive dust, sand drift, etc., all of whichare enemies of delicate .mechanical parts and, in due course of time,will detract from their accurate functioning and give rise to muchtrouble. It is evident that my simple and rugged design is free from allsuch-deficiencies.

Various minor changes may, of course, be made without departing from thespirit of the invention, and in this regard I do not mean to be limitedby the exemplified structure but, rather, by the claims.

What I claim is 1. In combination with a fishing rod, a tubular reelseat having near one of its ends and partly extending over itscircumference Jaw a pocket slotted along and near its open edge, aseat-conforming reel base plate with identical pocket-insertable andslot-fitting end portions for insertion of either of them in the pocketwith hook-and-eye engagement in itsislot, and a resilient ring slidableon said tubular seat of substantially oval form so as to allow, whenturned in shoving position, to be shoved without deflection over thenon-pocketed end of the assembled base plate and, when thereupon turnedin opposite locking position to tightly clamp the seat and base platewithin its deflected contour.

2. The combination in a fishing rod of a seat member, a reel base plateprovided with a terminal flange, and a resilient ring having an ovalcross-sectional form,,-and shaped so that in one position of rotation itmay be slid over the terminal flange of the base plate and in anotherposition of rotation it will grip both the seat member and the baseplate symmetrically by its own resilience.

3. The combination in a fishing rod of a seat member of arcuatecross-section, a reel base plate of circular cross section and providedwith a terminal flange, and a resilient ring having a symmetricalenlargement at one side sufficient to permit it to be passed over theterminal flange of the base plate when in one position of rotation, saidring having an internal contour causing a four point gripping contact onthe seat member and base plate when the ring is rotated half arevolution from the first named position. In testimony whereof I haveaflixed my signature.
